From 05572414cb96405fb357e2af3aa24ae691a9b4ab Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Thu, 14 May 2015 12:10:59 +0200 Subject: [PATCH] stmmac: add a generic dwmac driver Create a new driver around the generic device tree match strings in the stmmac platform code. This driver is intended to be used by all platforms that doesn't require any platform specific code to function or is using platform data. Signed-off-by: Joachim Eastwood Signed-off-by: David S.
